CURT VOGT, F BERLIN, GERMANY COIN COUNTING DEVICE Application filed April 7, 1930, Serial No. 442,156, and in Germany January 28-, 1930.

The invention provides a device for counting coins or the like in conjunction with counting machines wherein the coins are consecutively brought by driving rollers into engagement with a motion wheel which may be used for driving a counting or adding mechanism, and which releases a mechanism locking the coin chute leading to the motion 10 wheel. It is intended by means of the invention to render it possible to vary the number of revolutions of the motion wheel ad libitum and to regulate the motion wheel in sucha manner, that it executes a greater or lesser number of revolutions according to requirements, and by reason thereof transport the appropriate number of coins and then stops.

According, to the invention the coin locking; number is displaceably arranged on a motion ratchet bar connected with a toothed locking bar being moved tooth by tooth by means of the motion wheel driven by the coins under the influence of the driving rollers, and the ratchet bar is formed with a notch or excision so that when moved into the releasing position it releases the coin locking device which obstructs the mouth of the coin chute in front of the driving rollers.

A constructional example of the invention is shown in the accompanying drawin s.

ig. 1 shows a lateral view of the device for counting coins in one of its working positions and Fig. 2 shows the device in another position.

The coin supply chute 1- ends close to the driving rollers 2, which are arranged opposite one another, and grip the coins coming from the coin chute 1, and thereby cause them to engage the motion wheel 3 which is connected to a counting mechanism by means of transmission gears, (not shown), and which motion wheel is mounted on a spindle 4 in the housing 5 of the device. The motion wheel 3 is provided with a driving pin 6 which, at each revolution of. the wheel engages a cam disc 8pivotally mounted at 7, and carrying a motion pawl 10 which is pivoted at 11 and influenced by a spring 9. This pawl is arrangedto engage the toothed or ratchet motion bar 12, which latter is mounted to. slide in the walls 13 of the housing 5 ofthe device.

The ratchet motion bar 12 is provided at one of its extremities with a scale, inscribed for example with the numbers 10, 20, 30, 40, and and whose graduations are arranged to coincide with an index face 141 adjacent, one opening in the wall of the housing, when the motion pawl 10 has arrived at the end of a stroke and consequently strikes against a tooth of the ratchet motion bar. This ratchet bar is provided at its other extremity with an adjusting collar 15 which can be securely retained by means of the wing screw 17 in that position in which it limits the displacement of the ratchet motion bar and of the scale is limited in such a manner that only the appreciate corressponding portion of the scale protrudes from the other sideof the housing, which shows the number of coins it is desired to count.

The ratchet motion bar 12 is connected with a locking toothed gear 18 into which engages a locking pawl 21 pivotally mounted at 19 in the wall of the housing and influenced by a spring 20 which pawl is provided with an arm 22.

Oppositethe arm 22 is pivoted at point 23 a plate 24 which is provided with a notch or excision 25 and is acted upon by a spring 26 the tendency of the spring being at all times to press the plate when in its position of rest against a stop pin 27 fixed in the housing, as is shown in Fig. 1.. The plate 24 is provided with a projection 28 and a laterally projecting pin 29. The projection 28 projects into the path of a pin 30 on a U-shaped slide 32, hearing the coin locking device 31, this slide 32 being guided at 33 in the housing, and seated'by' means of one of its arms 34 on a sliding path 35 on the ratchet motion bar 12, which maintains the slide and the coin locking device in the raised release-positiom as in Fig. 1,. It is preferable to provide the arm 34 with a roller 36. The slide 32 is acted upon by a spring 37 which has the tendency to keep it in touch with the ratchet motion bar 12. The guide bar 38 of the slide 32 is provided with a head 39 with which engages an arm of a handle 41 pivotally mounted on the housing at point 40 by means of which the slide 32 can be lifted into the position shown in dotted lines in Fig. 2.

The ratchet motion bar 12 is formed at the'extremity of the sliding path 35 with a notch 42 into which the arm 32 engages, when the motion bar has executed a movement covering the whole row of figures. A tension spring 44 is connected at. 43' tothe motion ratchet rod 12 and at point 45 to the housing. Forthe purpose of limiting the displacement of the ratchet motion bar 12 it is formed with a longitudinal groove 46 into. which engages a pin 47 fixed to the housing.

Operation of the device will beas follows:

As is clearlyshown in Fig. 1, the ratchet bar is'so adjusted, that the 10 of the scale is visible this of course indicating that 10 coins are to be counted out and that the coin supply is then automatically stopped. In the position shownin the drawing the 10th coin is being gripped' by the'driving rollers and brought into engagement with the motion wheel 3, which'is just about to be moved round by of a revolution, by reason of which the pin 6 moves the motion pawl 8 and the toothed rack 12 forward by the mount of its last tooth, whereupon the sliding member 32 drops into the notch 42, as is shown in Fig. 2 in full lines, and the coin locking member moves to a position between the driving rollers 2, as shown in Fig.

- 2, and prevents any further supply of coins.

For the purpose of getting the device ready for the next counting operation, the lever 41 is depressed which is thereby moved into the position shown in dotted lines in Fig. 2. During this operation the sliding member 32 emerges from the notch 42 and releases the motion bar 12 whereupon it can be again set for a new count.

When the sliding member 32 is drawn up the pin 30 striking against the projection 28 on the plate 24 causes the top part of the plate to strike against the arm 22 of the locking pawl 21'and thereby raises the latter from the locking gear teeth. At the same time the pin .29 on the plate 24 pushes the motion pawl 10 downwards, as is shown in dash lines in Fig. 2. At this moment the motion bar is completely released and can again be displaced.

Y The number of teeth on the rack bar 12 depends on the number of the coin counting stages, which are indicated on the scale. In the example shown six counting stages or proceedings are shown, but the deviceis of course not limitedto this number, on the contrary 'anynumber ofstages or separate tively to-said member towards its initial position, and means to permit said memberto, drop from said guide-portion when the latter has reached said initial position whereby to stop. the delivery of coins and lock said bar. A v v v 2. In a coin counting device, the'combinw tion of a tensioned slidable bar showing a linear scale indicating a series of numbers of coins and adjustable upon a predetermined number of said scale by the operator, said bar being provi'ded with a guide portion and a slotarranged at the end of said guide portion, a sliding coin stop member supported by and riding upon said guidepor tion,' and means for shifting said bar to displace said scale during the counting operation and to bring said slot into the path of said riding member when a predetermined number of coins has been counted.

3. In a coin'counting device, the combination of a tensioned slidable index bar showing a linear scale indicating a series of num bers of coins and being adjustable on an index of said scale by the operator, said bar being provided with a guide portion and a slot arranged at the end of said guide portion, a riding member supported by and riding upon said guide portion, said bar being provided with rack portions, a catch pawl. and a switching pawlv cooperating with the rack portions, a coin delivery wheel actuating said switching pawl to cause said riding member to drop from the guide portion into the slot of said index bar.

interrupt coin delivery.

5. In a coin counting device, the combination of a tensioned slidable bar adjustable by the operator into a chosen position corresponding to the desired number of coins to be ejected, said bar carrying a guide portion and having a slot at one end of the guide portion, a sliding member supported by and riding upon said guide portion, means for shifting said guide portion to bring said slot into the path of said riding member when a pretermined number of coins has been counted, and means for re tracting said riding member to reset it upon said guide portion for preparing a new counting operation.

6. In a coin counting device, the combination of a tensioned slidablc bar adjustable by the operator into a predetermined starting position corresponding to a desired number of coins to be ejected, a sliding member supported by and riding upon said bar, said bar having a slot in which said member initially engages, means for retracting said riding member to set it upon 5 said bar for preparing a counting opera-- tion, said bar being provided with rack portions, a catch pawl and a switching pawl cooperating with said rack portions, means actuated b coins fed to operate said switching paw for starting said bar, and a twoarmed spring pressed lever, one of said arms rojecting into the path of said riding memer, the other arm adapted to strike against said catch pawl to release it when said 5 riding member is retracted by the operator to set it upon the bar to permit displacement of the latter into a starting position.

In testimony whereof I have signed my 40 name to this specification.
